A shrub or small tree, growing up to 4.5 m tall, in sand over limestone. Tiny, white woolly flowers on white woolly stems are borne in mid winter to late spring. They are held above the foliage, and from a distance resemble smoke. The large leaves often have three prominent veins, prompting the species name from Latin: triplus: “group of three” and nervis “nerve” (veins).
